Abstract
A process for stabilising particulate alkali metal percarbonate involves coating it with an aqueous solution, preferably concentrated, of a non-reducing oligomeric saccharide, preferably sucrose and especially together with an inorganic salt co-coating agent. The preferred co-coating agents are alkali metal silicate, sulphate, carbonate and carbonate chloride. Coated percarbonate is provided having an excellent combination of solubility, and stability, even with low amounts of coating agent.
